CSP Bypass Vulnerability in Firefox < 60

CVE-2018-5175 · MEDIUM Severity

AV:N/AC:M/AU:N/C:N/I:P/A:N

A mechanism to bypass Content Security Policy (CSP) protections on sites that have a "script-src" policy of "'strict-dynamic'". If a target website contains an HTML injection flaw an attacker could inject a reference to a copy of the "require.js" library that is part of Firefox's Developer Tools, and then use a known technique using that library to bypass the CSP restrictions on executing injected scripts. This vulnerability affects Firefox < 60.
